HSA compliance

[Macker]

Hey guys,

Just having a discussion with various other nerds on extremetech and I was wondering if it would be at all possible to make VRay render on GPU on an HSA system? The current GPU bottleneck for me is RAM, so to be able to use the main RAM on the motherboard whilst rendering on GPU would be amazing.

I see that this architecture uses AMD graphic cards, which have problems to work with our Rt/GPU engine (not all, but most of them). Are you able to run a test with RT/GPU - OpenCL engine on this machine ? It could be done even with the demo version of V-Ray 3.

I will try to get some more information from our devs.

We currently use NVidia graphics at the moment for that very reason - but on large jobs, the vram simply isn't enough and HSA is the only architecture that allows the GPU to utilise the main system RAM. We'd switch in a heartbeat if such a system worked.

Hi Macker,

I just checked the specification of the HSA system and the exact AMD GPU installed is Radeon HD 7660G, 6 compute units, 685MHz.
Unfortunately we don't have the same model here to test its compatibility with V-Ray RT/GPU, therefore the best way is to perform a test (using the latest graphic drivers) and see the results. Is that possible at all ?

Nope, we don't have the hardware here either I'm afraid.
